摘　　要：目的:探讨牙龈环切辅助牙周炎患牙正畸压低对牙周炎患牙预后的影响。方法:选取34颗伴有附着丧失的牙周炎患牙,牙周基础治疗后开展正畸治疗,在排齐整平阶段配合牙龈环切术,治疗前后使用平行投照根尖片来测量牙冠和牙根比例的变化以及釉牙骨质界-牙槽嵴顶高度的变化量。结果:牙龈环切辅助正畸经过6～9个月完成排齐整平,患牙覆盖改善,覆牙合正常,牙弓spee曲线减小,牙龈无红肿,牙周袋无加深,无明显探诊出血。患牙平均被压入(0.73±0.56)mm,冠根比例改善了(13±12)%。结论:牙龈环切术辅助牙周炎的正畸压入治疗有利于牙周炎的预后。Aim ： To investigate the effect of intrusion of the teeth at the aligning and leveling stage after circumferen- tial supracrestal fibrotomy. Methods：During aligning and leveling stage of orthodontic therapy, 34 teeth with attachment loss were treated based on circumferential supracrestal fibrotomy. Parallel periapical radiographic technique was used to measure changes in crown-root ratio and cemento-enamel junction and alveolar crest height before and after treatment. Re- suits： The aligning and leveling stage of the orthodontic treatment with circumferential supracrestal fibrotomy spent 6 - 9 months. The overjet was improved, the overbite became normal, the curve of spee was decreased,and the periodontal health maintained as well. Specifically, the average amount of intrusion into the bone was about （0.73 ±O. 56） ram, and crown- root ratio was improved by （13 ± 12）%. Conclusion： The orthodontic treatment with circumferential supracrestal fibroto- my and the teeth intrusion is helpful for prognosis of periodontitis.
